Illness to prevent

Measles and Rubella

Measles
Measles is highly contagious and has severe symptoms if contracted. Measles usually begins with cold-like symptoms such as fever, coughing, and a runny nose. A fever of approximately 38oC lasts for a while followed by a temporary decrease, then the fever reaches up to very high accompanied with measles rash all over the body. High fever will continue for 3 to 4 days and coughing will worsen. Complications such as otitis media, pneumonia, and encephalitis, can easily occur, and death may result in some cases.

Rubella
Rubella begins with mild cold symptoms, and then fever, rash and swelling of the lymph nodes may occur. Children will have mild symptoms, but adults who get this illness may develop severe symptoms. In particular, if women in the early stage of pregnancy contract this illness, there will be a high probability that their babies will be born with congenital rubella syndrome.
